Bandwidth Allocation Policy using the Game Theory Model in Heterogeneous Wireless Networks

In Heterogeneous Wireless Network (WHN), a Mobile Device (MD) can be connected with multiple access technologies available in a particular geographical area. Selection of appropriate access technology is a challenge for the MD where game theory policy can be applied. Shapley Value is one of the game-theoretic models that can be applied to allocate appropriate bandwidth for i number of users for k number of services from N access technologies. It proposes the fairest allocation of the collectively gained profits among the collaborative players in the game. The primary focus is to find the relative contribution of every player in a cooperative game. This paper has drawn a numerical analysis of Shapley Value for three wireless access technologies, namely WiFi, Cellular and WiMAX. It has been shown how much bandwidth can be allocated from an access technology for a required bandwidth for a specific service. It can be noted from the results that 225Kbps, 141.67Kbps and 233.33Kbps can be allocated from WiFi, Cellular and WiMAX respectively to transmit the 600Kbps data in an HWN network.
